14、WARNING 1.Never attempt to machine a workpiece without first checking the operation of the machine. Before starting a production run, ensure that the machine is operating correctly by performing a trial run using, for example, the single block, feedrate override, or machine lock function or by opera
15、ting the machine with neither a tool nor workpiece mounted. Failure to confirm the correct operation of the machine may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user. 2.Before operating the machine, thoroughly check
16、 the entered data. Operating the machine with incorrectly specified data may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user. 3.Ensure that the specified feedrate is appropriate for the intended operation. Generally,
17、for each machine, there is a maximum allowable feedrate. The appropriate feedrate varies with the intended operation. Refer to the manual provided with the machine to determine the maximum allowable feedrate. If a machine is run at other than the correct speed, it may behave unexpectedly, possibly c
18、ausing damage to the workpiece and/or machine itself, or injury to the user. 4.When using a tool compensation function, thoroughly check the direction and amount of compensation. Operating the machine with incorrectly specified data may result in the machine behaving unexpectedly, possibly causing d
19、amage to the workpiece and/or machine itself, or injury to the user. 5.The parameters for the CNC and PMC are factoryset. Usually, there is not need to change them. When, however, there is not alternative other than to change a parameter, ensure that you fully understand the function of the paramete
20、r before making any change. Failure to set a parameter correctly may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user. 6.Immediately after switching on the power, do not touch any of the keys on the MDI panel until the
21、 position display or alarm screen appears on the CNC unit. Some of the keys on the MDI panel are dedicated to maintenance or other special operations. Pressing any of these keys may place the CNC unit in other than its normal state. Starting the machine in this state may cause it to behave unexpecte
22、dly. 7.The operators manual and programming manual supplied with a CNC unit provide an overall description of the machines functions, including any optional functions. Note that the optional functions will vary from one machine model to another. Therefore, some functions described in the manuals may
23、 not actually be available for a particular model. Check the specification of the machine if in doubt. B62564E1/02SAFETY PRECAUTIONS s4 WARNING 8.Some functions may have been implemented at the request of the machinetool builder. When using such functions, refer to the manual supplied by the machine
24、tool builder for details of their use and any related cautions. NOTE Programs, parameters, and macro variables are stored in nonvolatile memory in the CNC unit. Usually, they are retained even if the power is turned off. Such data may be deleted inadvertently, however, or it may prove necessary to d
25、elete all data from nonvolatile memory as part of error recovery. To guard against the occurrence of the above, and assure quick restoration of deleted data, backup all vital data, and keep the backup copy in a safe place. B62564E1/02SAFETY PRECAUTIONS s5 3 WARNINGS AND CAUTIONS RELATED TO PROGRAMMI
26、NG This section covers the major safety precautions related to programming. Before attempting to perform programming, read the supplied operators manual and programming manual carefully such that you are fully familiar with their contents. WARNING 1.Coordinate system setting If a coordinate system i
27、s established incorrectly, the machine may behave unexpectedly as a result of the program issuing an otherwise valid move command. Such an unexpected operation may damage the tool, the machine itself, the workpiece, or cause injury to the user. 2.Positioning by nonlinear interpolation When performin
28、g positioning by nonlinear interpolation (positioning by nonlinear movement between the start and end points), the tool path must be carefully confirmed before performing programming. Positioning involves rapid traverse. If the tool collides with the workpiece, it may damage the tool, the machine it
29、self, the workpiece, or cause injury to the user. 3.Function involving a rotation axis When programming polar coordinate interpolation or normaldirection (perpendicular) control, pay careful attention to the speed of the rotation axis. Incorrect programming may result in the rotation axis speed beco
30、ming excessively high, such that centrifugal force causes the chuck to lose its grip on the workpiece if the latter is not mounted securely. Such mishap is likely to damage the tool, the machine itself, the workpiece, or cause injury to the user. 4.Inch/metric conversion Switching between inch and m
31、etric inputs does not convert the measurement units of data such as the workpiece origin offset, parameter, and current position. Before starting the machine, therefore, determine which measurement units are being used. Attempting to perform an operation with invalid data specified may damage the to
32、ol, the machine itself, the workpiece, or cause injury to the user. 5.Constant surface speed control When an axis subject to constant surface speed control approaches the origin of the workpiece coordinate system, the spindle speed may become excessively high. Therefore, it is necessary to specify a
33、 maximum allowable speed. Specifying the maximum allowable speed incorrectly may damage the tool, the machine itself, the workpiece, or cause injury to the user. B62564E1/02SAFETY PRECAUTIONS s6 WARNING 6.Stroke check After switching on the power, perform a manual reference position return as requir
34、ed. Stroke check is not possible before manual reference position return is performed. Note that when stroke check is disabled, an alarm is not issued even if a stroke limit is exceeded, possibly damaging the tool, the machine itself, the workpiece, or causing injury to the user. 7.Tool post interfe
35、rence check A tool post interference check is performed based on the tool data specified during automatic operation. If the tool specification does not match the tool actually being used, the interference check cannot be made correctly, possibly damaging the tool or the machine itself, or causing in
36、jury to the user. After switching on the power, or after selecting a tool post manually, always start automatic operation and specify the tool number of the tool to be used. 8.Absolute/incremental mode If a program created with absolute values is run in incremental mode, or vice versa, the machine m
37、ay behave unexpectedly. 9.Plane selection If an incorrect plane is specified for circular interpolation, helical interpolation, or a canned cycle, the machine may behave unexpectedly. Refer to the descriptions of the respective functions for details. 10.Torque limit skip Before attempting a torque l
38、imit skip, apply the torque limit. If a torque limit skip is specified without the torque limit actually being applied, a move command will be executed without performing a skip. 11.Programmable mirror image Note that programmed operations vary considerably when a programmable mirror image is enable
39、d. 12.Compensation function If a command based on the machine coordinate system or a reference position return command is issued in compensation function mode, compensation is temporarily canceled, resulting in the unexpected behavior of the machine. Before issuing any of the above commands, therefo
40、re, always cancel compensation function mode. B62564E1/02SAFETY PRECAUTIONS s7 4 WARNINGS AND CAUTIONS RELATED TO HANDLING This section presents safety precautions related to the handling of machine tools. Before attempting to operate your machine, read the supplied operators manual and programming
41、manual carefully, such that you are fully familiar with their contents. WARNING 1.Manual operation When operating the machine manually, determine the current position of the tool and workpiece, and ensure that the movement axis, direction, and feedrate have been specified correctly. Incorrect operat
42、ion of the machine may damage the tool, the machine itself, the workpiece, or cause injury to the operator. 2.Manual reference position return After switching on the power, perform manual reference position return as required. If the machine is operated without first performing manual reference posi
43、tion return, it may behave unexpectedly. Stroke check is not possible before manual reference position return is performed. An unexpected operation of the machine may damage the tool, the machine itself, the workpiece, or cause injury to the user. 3.Manual numeric command When issuing a manual numer
44、ic command, determine the current position of the tool and workpiece, and ensure that the movement axis, direction, and command have been specified correctly, and that the entered values are valid. Attempting to operate the machine with an invalid command specified may damage the tool, the machine i
45、tself, the workpiece, or cause injury to the operator. 4.Manual handle feed In manual handle feed, rotating the handle with a large scale factor, such as 100, applied causes the tool and table to move rapidly. Careless handling may damage the tool and/or machine, or cause injury to the user. 5.Disab
46、led override If override is disabled (according to the specification in a macro variable) during threading, rigid tapping, or other tapping, the speed cannot be predicted, possibly damaging the tool, the machine itself, the workpiece, or causing injury to the operator. 6.Origin/preset operation Basi
47、cally, never attempt an origin/preset operation when the machine is operating under the control of a program. Otherwise, the machine may behave unexpectedly, possibly damaging the tool, the machine itself, the tool, or causing injury to the user. B62564E1/02SAFETY PRECAUTIONS s8 WARNING 7.Workpiece
48、coordinate system shift Manual intervention, machine lock, or mirror imaging may shift the workpiece coordinate system. Before attempting to operate the machine under the control of a program, confirm the coordinate system carefully. If the machine is operated under the control of a program without
49、making allowances for any shift in the workpiece coordinate system, the machine may behave unexpectedly, possibly damaging the tool, the machine itself, the workpiece, or causing injury to the operator. 8.Software operators panel and menu switches Using the software operators panel and menu switches, in combination with the MDI panel, it is possible to specify operations not supported by the machine operators panel, such as mode change, override value change, and jog feed commands. Note, however, that if the MDI panel keys are operated inadvertently, the m
